我正在尝试将其解析为JSON数组对象，当我在Google中搜索它时，我找到了以下解决方案：

JSONArray jsonArray = new JSONArray("path_to_file_to_parse");

但是当我在我的代码中写入它时，我收到了一个错误。还有另一种方法吗？

我正在使用json-simple version 1.1

你看过Jackson Tree Model吗？

//first, you create a mapper object
ObjectMapper mapper = new ObjectMapper();

//then you create a JsonNode instance representing your JSON root structure
//you will need to define json yourself to run the code.
JsonNode root = null;
try {
    root = mapper.readTree(json);
} catch (IOException e) {
    System.out.println("Some Error");
}

//here you get the list of your session nodes
JsonNode list = root.path("LiveSessionDataCollection");

//then you can iterate through them and get any inner value
for (JsonNode session : list) {
    //for example, you can get the create date or live session id.
    System.out.println(session.path("CreateDate"));
    System.out.println(session.path("LiveSessionId"));
}

我可能不完全理解你的问题，但我认为这就是你所追求的。

使用Java将String转换为Object Json Array
